As the returns came in from South Carolina Saturday night, showing Donald Trump winning a decisive victory, a note of nervous desperation crept into the commentary.

Political analysts pointed out repeatedly that if all of the votes for Marco Rubio, Ted Cruz, John Kasich, Jeb Bush and Ben Carson were added up, they far exceeded the Trump vote.

Why this sudden interest in arithmetic?

If the field can be winnowed, we were told, if Carson and Kasich can be persuaded to follow Bush and get out, if Cruz can be sidelined, if we can get a one-on-one Rubio-Trump race, Trump can be stopped.

Behind the thought is the wish. Behind the wish is the hope, the prayer that all the non-Trump voters are anti-Trump voters.

Sen. Goldwater had just won the winner-take-all California primary, defeating Gov. Nelson Rockefeller, assuring himself of enough delegates to go over the top on the first ballot at the Cow Palace in San Francisco.

Goldwater won his nomination and went down in a historic defeat, but became a beloved figure and the father of modern conservatism.

Of those who turned their backs on Goldwater that fall, none ever won a presidential nomination. Of those who stood by Barry that fall, Richard Nixon and Ronald Reagan, both would win the GOP nomination twice, and the presidency twice.

And the conservative movement would hold veto power over party nominees and become the dominant philosophy of the GOP.

Folks forget. Not only were there "liberal Republicans" and "moderate Republicans" back then, they dominated the landscape. Yet rare is the Republican today who would describe himself in such terms.

Which brings us back to the anti-Trump cabal.

While their immediate goal is to deny him the nomination, do they really think that if the party nominates Rubio, things can be again as they were before Trump? Do they not see that America and the West are undergoing a series of crises that will change our world forever?

Whatever one may think of Trump's talk of building a wall, does anyone think the United States is not going to have to build a security fence to defend our bleeding 2,000-mile border?

Given the huge trade deficits with China, Japan, Mexico and the EU, the hemorrhaging of manufacturing, the stagnation of wages and the decline of the middle class, does anyone think that if Trump is turned back, the GOP can continue on being a free-trade party financed by the Beltway agents of transnational corporations?

Absent some major attack on the homeland, do our foreign policy elites believe the American people would support new U.S. interventions to defeat, occupy and tutor Third World nations in liberal democracy?

Trump is winning because, on immigration, amnesty, securing our border and staying out of any new crusades for democracy, he has tapped into the most powerful currents in politics: economic populism and "America First" nationalism.

Look at the crowds Trump draws. Look at the record turnouts in Republican caucuses and primaries.
